function Connect-DbaInstance { <# .SYNOPSIS Creates a robust, reusable SQL Server object. .DESCRIPTION This command creates a robust, reusable sql server object. It is robust because it initializes properties that do not cause enumeration by default. It also supports both Windows and SQL Server authentication methods, and detects which to use based upon the provided credentials. By default, this command also sets the connection's ApplicationName property to "dbatools PowerShell module - dbatools.io - custom connection". If you're doing anything that requires profiling, you can look for this client name. Alternatively, you can pass in whichever client name you'd like using the -ClientName parameter. There are a ton of other parameters for you to explore as well. See https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring.aspx and https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnectionstringbuilder.aspx, and https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.aspx To execute SQL commands, you can use $server.ConnectionContext.ExecuteReader($sql) or $server.Databases['master'].ExecuteNonQuery($sql) .PARAMETER SqlInstance The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Credential object used to connect to the SQL Server Instance as a different user. This can be a Windows or SQL Server account. Windows users are determined by the existence of a backslash, so if you are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash. .PARAMETER Database The database(s) to process. This list is auto-populated from the server. .PARAMETER AppendConnectionString Appends to the current connection string. Note that you cannot pass authentication information using this method. Use -SqlInstance and optionally -SqlCredential to set authentication information. .PARAMETER ApplicationIntent Declares the application workload type when connecting to a server. Valid values are "ReadOnly" and "ReadWrite". .PARAMETER BatchSeparator A string to separate groups of SQL statements being executed. By default, this is "GO". .PARAMETER ClientName By default, this command sets the client's ApplicationName property to "dbatools PowerShell module - dbatools.io". If you're doing anything that requires profiling, you can look for this client name. Using -ClientName allows you to set your own custom client application name. .PARAMETER ConnectTimeout The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. Valid values are integers between 0 and 2147483647. When opening a connection to a Azure SQL Database, set the connection timeout to 30 seconds. .PARAMETER EncryptConnection If this switch is enabled, SQL Server uses SSL encryption for all data sent between the client and server if the server has a certificate installed. For more information, see Connection String Syntax. https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/connection-string-syntax Beginning in .NET Framework 4.5, when TrustServerCertificate is false and Encrypt is true, the server name (or IP address) in a SQL Server SSL certificate must exactly match the server name (or IP address) specified in the connection string. Otherwise, the connection attempt will fail. For information about support for certificates whose subject starts with a wildcard character (*), see Accepted wildcards used by server certificates for server authentication. https://support.microsoft.com/en-us/help/258858/accepted-wildcards-used-by-server-certificates-for-server-authenticati .PARAMETER FailoverPartner The name of the failover partner server where database mirroring is configured. If the value of this key is "" (an empty string), then Initial Catalog must be present in the connection string, and its value must not be "". The server name can be 128 characters or less. If you specify a failover partner but the failover partner server is not configured for database mirroring and the primary server (specified with the Server keyword) is not available, then the connection will fail. If you specify a failover partner and the primary server is not configured for database mirroring, the connection to the primary server (specified with the Server keyword) will succeed if the primary server is available. .PARAMETER LockTimeout Sets the time in seconds required for the connection to time out when the current transaction is locked. .PARAMETER MaxPoolSize Sets the maximum number of connections allowed in the connection pool for this specific connection string. .PARAMETER MinPoolSize Sets the minimum number of connections allowed in the connection pool for this specific connection string. .PARAMETER MultipleActiveResultSets If this switch is enabled, an application can maintain multiple active result sets (MARS). If this switch is not enabled, an application must process or cancel all result sets from one batch before it can execute any other batch on that connection. .PARAMETER MultiSubnetFailover If this switch is enabled, and your application is connecting to an AlwaysOn availability group (AG) on different subnets, detection of and connection to the currently active server will be faster. For more information about SqlClient support for Always On Availability Groups, see https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/sql/sqlclient-support-for-high-availability-disaster-recovery .PARAMETER NetworkProtocol Explicitly sets the network protocol used to connect to the server. Valid values are "TcpIp","NamedPipes","Multiprotocol","AppleTalk","BanyanVines","Via","SharedMemory" and "NWLinkIpxSpx" .PARAMETER NonPooledConnection If this switch is enabled, a non-pooled connection will be requested. .PARAMETER PacketSize Sets the size in bytes of the network packets used to communicate with an instance of SQL Server. Must match at server. .PARAMETER PooledConnectionLifetime When a connection is returned to the pool, its creation time is compared with the current time and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. This is useful in clustered configurations to force load balancing between a running server and a server just brought online. A value of zero (0) causes pooled connections to have the maximum connection timeout. .PARAMETER SqlExecutionModes The SqlExecutionModes enumeration contains values that are used to specify whether the commands sent to the referenced connection to the server are executed immediately or saved in a buffer. Valid values include "CaptureSql", "ExecuteAndCaptureSql" and "ExecuteSql". .PARAMETER StatementTimeout Sets the number of seconds a statement is given to run before failing with a timeout error. .PARAMETER TrustServerCertificate When this switch is enabled, the channel will be encrypted while bypassing walking the certificate chain to validate trust. .PARAMETER WorkstationId Sets the name of the workstation connecting to SQL Server. .PARAMETER SqlConnectionOnly Instead of returning a rich SMO server object, this command will only return a SqlConnection object when setting this switch. .PARAMETER AzureUnsupported Terminate if Azure is detected but not supported .PARAMETER AzureDomain By default, this is set to database.windows.net In the event your AzureSqlDb is not on a database.windows.net domain, you can set a custom domain using the AzureDomain parameter. This tells Connect-DbaInstance to login to the database using the method that works best with Azure. .PARAMETER MinimumVersion Terminate if the target SQL Server instance version does not meet version requirements .PARAMETER AuthenticationType Basically used to force AD Universal with MFA Support when other types have been detected .PARAMETER Tenant The TenantId for an Azure Instance .PARAMETER Thumbprint Thumbprint for connections to Azure MSI .PARAMETER Store Store where the Azure MSI certificate is stored .PARAMETER DisableException By default in most of our commands, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This command, however, gifts you with "sea of red" exceptions, by default, because it is useful for advanced scripting. Using this switch turns our "nice by default" feature on which makes errors into pretty warnings. .NOTES Tags: Connect, Connection Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Connect-DbaInstance .EXAMPLE PS C:\> Connect-DbaInstance -SqlInstance sql2014 Creates an SMO Server object that connects using Windows Authentication .EXAMPLE PS C:\> $wincred = Get-Credential ad\sqladmin PS C:\> Connect-DbaInstance -SqlInstance sql2014 -SqlCredential $wincred Creates an SMO Server object that connects using alternative Windows credentials .EXAMPLE PS C:\> $sqlcred = Get-Credential sqladmin PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -SqlCredential $sqlcred Login to sql2014 as SQL login sqladmin. .EXAMPLE PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -ClientName "my connection" Creates an SMO Server object that connects using Windows Authentication and uses the client name "my connection".
